Remarks
Important
You are viewing documentation for the legacy WPF Scheduler control. If you’re starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.
The AppointmentDeleting event is raised before an appointment is deleted and allows you to cancel the deletion of an appointment. The event parameter’s PersistentObjectEventArgs.Object property allows the processed appointment to be identified. To prevent it from being deleted, set the PersistentObjectCancelEventArgs.Cancel property to true.
